Data Jamboree 2/Annotation Experiment

Background:

The curation experiment was given to five curators on the third day of the second data jamboree. The goals of the experiment were to assess curation consistency among a group of new curators, and to identify areas of improvement in curator training, ontology development, and software improvement.

Participant Training:

Only one of the five curators had experience using Phenex prior to the data roundup. Training for all curators consisted of:

Results:

A summary of results for each character is presented below, and a comparison to the first consistency experiment given at the Data Jamboree I is presented in this table. Additional notes on the discussion of results with curators and advisors can be found here.

Character Summary and Suggestions for Improvement

1. Presence or absence of intercalar: (0) present; (1) absent.3

2. Opercle depth to width ratio: (0) less than two; (1) about two or greater than two. Essentially, this character distinguishes between those taxa with a short, relatively broad opercle and those with a tall relatively slender opercle.2

3. Number of unbranched plus branched pelvic-fin rays: (0) 11; (1) nine; (2) more than 11.3

4. Basihyal: (0) present and ossified; (1) present and cartilaginous; (2) absent.1

5. Position of anterior margin of nasal: (0) falling short of lateral process of mesethmoid (= lateral ethmoid wing of Weitzman, 1962); (1) extending anteriorly to overlie or extend beyond lateral process of mesethmoid.3

6. Number of hypurals in upper lobe of caudal fin: (0) four; (1) three.2

7. Presence or absence of medially directed, spine-like process on ventral surface of post-temporal: (0) present; (1) absent.3

8. Presence or absence of contact between frontal and pterotic: (0) frontal and pterotic bones in contact; (1) pterotic excluded from contact with frontal by sphenotic.3

9. Orientation of infrapharyngobranchial 1: (0) proximal tip anteriorly directed; (1) proximal tip posteriorly directed.1

10. Dermosphenotic (0) triangular; (1) triradiate; (2) tubular.1
